What is the target weight loss range for patients with knee osteoarthritis?

• A. 2-4% of body weight
• B. 5-7.5% of body weight
• C. 8-10% of body weight
• D. 12-15% of body weight

Answer: (B)

Weight loss reduces the load the knee joint must bear during each step, which helps lessen pain and improve function in knee osteoarthritis. A modest reduction of about 5-7.5% of body weight is enough to produce meaningful clinical improvements and is a realistic, commonly targeted goal for most patients. For example, losing 5–7.5% can significantly lower knee joint loading over daily activities, making this range an effective balance between impact and feasibility. While losing more weight can offer additional benefits, 5–7.5% is the standard target often emphasized in guidelines and practice. Smaller losses around 2–4% may not consistently relieve symptoms, and higher targets like 8–10% or more, though beneficial, are harder to achieve and not the primary target in typical management.
